Pelican Panel Plugins

Pelican is an open-source game server management panel built on Laravel + FilamentPHP. Plugins let you add functionality without touching core files.

⚠️ The plugin system is still in active development — some features may change.

Quick Reference

📖 Detailed Guides:

• FilamentPHP Patterns - Resources, pages, widgets, actions, relation managers
• Advanced Patterns - Models, services, routes, commands, events
• Complete Plugin Walkthrough - Step-by-step example

Scaffolding a New Plugin

Run inside the panel directory (/var/www/pelican by default):

php artisan p:plugin:make

This creates the basic structure with plugin.json, main plugin class, service provider, and config file.

Critical: The plugin folder name must exactly match the id field in plugin.json.

Everything in standard Laravel locations is auto-discovered: migrations, providers, commands, policies.

Main Plugin Class

Located in src/{ClassName}.php:

namespace MyName\MyPlugin;

use Filament\Contracts\Plugin;
use Filament\Panel;

class MyPlugin implements Plugin
{
    public function getId(): string
    {
        return 'my-plugin';
    }

    public function register(Panel $panel): void
    {
        $id = str($panel->getId())->title(); // "Admin", "App", "Server"

        // Auto-discover Filament components
        $panel->discoverPages(
            plugin_path($this->getId(), "src/Filament/$id/Pages"),
            "MyName\\MyPlugin\\Filament\\$id\\Pages"
        );
        $panel->discoverResources(
            plugin_path($this->getId(), "src/Filament/$id/Resources"),
            "MyName\\MyPlugin\\Filament\\$id\\Resources"
        );
        $panel->discoverWidgets(
            plugin_path($this->getId(), "src/Filament/$id/Widgets"),
            "MyName\\MyPlugin\\Filament\\$id\\Widgets"
        );
    }

    public function boot(Panel $panel): void
    {
        //
    }
}

The Three Filament Panels

Panel ID	Area	Use Case
admin	Admin area	Full CRUD for resources, settings, management
app	Server list	Minimal UI (no nav by default)
server	Server management	Tenant-scoped (current server context)

Enabling Navigation on app Panel

use App\Filament\App\Resources\Servers\ServerResource;
use App\Enums\CustomizationKey;

public function register(Panel $panel): void
{
    parent::register($panel);

    if ($panel->getId() === 'app') {
        ServerResource::embedServerList();
        $panel->navigation(true);
        $panel->topbar(function () {
            $nav = user()?->getCustomization(CustomizationKey::TopNavigation);
            return in_array($nav, ['topbar', 'mixed', true], true);
        });
        $panel->clearCachedComponents();
    }
}

Extending Core Resources

Call static methods on core classes inside a service provider's register():

use App\Filament\Admin\Resources\Users\UserResource;
use App\Filament\Admin\Resources\Servers\ServerResource;
use App\Models\Role;

public function register(): void
{
    // Add a relation manager tab
    ServerResource::registerCustomRelations(MyRelationManager::class);

    // Register permissions
    Role::registerCustomDefaultPermissions('myModel');
    Role::registerCustomModelIcon('myModel', 'tabler-star');
}

Available customization traits (check app/Traits/Filament/ for all):

• CanModifyResource - Relation managers, custom actions
• CanCustomizePage - Widgets, header actions
• CanModifyForm / CanModifyTable - Form/table hooks

Plugin Settings

Implement HasPluginSettings on your main class:

use App\Contracts\Plugins\HasPluginSettings;
use App\Traits\EnvironmentWriterTrait;
use Filament\Forms\Components\TextInput;
use Filament\Notifications\Notification;

class MyPlugin implements Plugin, HasPluginSettings
{
    use EnvironmentWriterTrait;

    public function getSettingsForm(): array
    {
        return [
            TextInput::make('api_key')
                ->required()
                ->default(fn () => config('my-plugin.api_key')),
        ];
    }

    public function saveSettings(array $data): void
    {
        $this->writeToEnvironment([
            'MY_PLUGIN_API_KEY' => $data['api_key'],
        ]);

        Notification::make()->title('Settings saved')->success()->send();
    }
}

Always prefix env vars with your plugin ID to avoid conflicts.

Permissions

Admin Role Permissions

In your service provider's register():

use App\Models\Role;

// Shorthand: registers viewList, view, create, update, delete
Role::registerCustomDefaultPermissions('myModel');

// Custom permissions
Role::registerCustomPermissions([
    'myModel' => ['export', 'approve'],
    'server'  => ['customAction'], // extend existing model
]);

// Optional: icon for permission group
Role::registerCustomModelIcon('myModel', 'tabler-star');

Subuser Permissions

use App\Models\Subuser;

// New permission group
Subuser::registerCustomPermissions('myFeature', ['read', 'write'], 'tabler-bolt', false);

// Append to existing group
Subuser::registerCustomPermissions('console', ['myCustomAction']);

Routes

Create a RouteServiceProvider in src/Providers/:

use Illuminate\Foundation\Support\Providers\RouteServiceProvider;
use Illuminate\Support\Facades\Route;

class MyPluginRoutesProvider extends RouteServiceProvider
{
    public function boot(): void
    {
        $this->routes(function () {
            // Simple route
            Route::get('/my-plugin/test', [TestController::class, 'index'])
                ->name('my-plugin.test');

            // Load from file
            Route::prefix('/my-plugin')
                ->group(plugin_path('my-plugin', 'routes/web.php'));

            // Append to client API
            Route::middleware(['api', 'client-api', 'throttle:api.client'])
                ->prefix('/api/client/servers/{server}')
                ->scopeBindings()
                ->group(plugin_path('my-plugin', 'routes/api-client.php'));
        });
    }
}

Models & Relationships

Add Relationship to Core Models

In your service provider's boot():

use App\Models\Server;
use MyPlugin\Models\Ticket;

public function boot(): void
{
    Server::resolveRelationUsing('tickets', fn (Server $server) => 
        $server->hasMany(Ticket::class, 'server_id', 'id')
    );
}

Now $server->tickets works everywhere.

Policies

use App\Policies\DefaultAdminPolicies;

class MyModelPolicy
{
    use DefaultAdminPolicies;

    protected string $modelName = 'myModel';
}

This automatically checks admin role permissions based on the registered model name.

Translations

Place in lang/{locale}/ (e.g., lang/en/strings.php):

return [
    'welcome' => 'Welcome',
    'item' => 'Item|Items', // Pluralization
];

Usage:

trans('my-plugin::strings.welcome')
trans_choice('my-plugin::strings.item', 2) // "Items"

Views

Place in resources/views/:

view('my-plugin::my-view')
// → plugins/my-plugin/resources/views/my-view.blade.php

Common Patterns

FilamentPHP Components

See FilamentPHP Patterns for:

• Resources (CRUD interfaces)
• Pages (custom pages)
• Widgets (dashboard components)
• Relation Managers (manage related records)
• Custom Actions (reusable buttons)
• Form components (inputs, selects, toggles)
• Table columns and filters

Advanced Patterns

See Advanced Patterns for:

• Model events and hooks
• Enums with Filament interfaces
• Service classes
• HTTP controllers and API routes
• Artisan commands and scheduling
• HTTP macros for external APIs
• Database migrations
• Error handling

Complete Example

See Complete Plugin Walkthrough for a step-by-step guide building a "Server Notes" plugin.

Publishing a Plugin

1. Open plugin.json and remove the meta block (internal use only)
2. Zip the entire plugin folder
3. Share the zip — users install via panel UI Import button or manually drop into plugins/

Publish to the community:

• GitHub: pelican-dev/plugins
• Discord: #plugins channel at discord.gg/pelican-panel

Tips & Gotchas

• Namespace in plugin.json: Use \\ (double backslash) for namespace separators
• Migration naming: Use numeric prefixes (001_, 002_) to control execution order
• Environment variables: Always prefix with your plugin ID (e.g., MY_PLUGIN_*)
• Panel context: Use Filament::getTenant() to get current server in server panel
• Auto-discovery: Service providers, commands, migrations, and policies are auto-discovered
• Relation managers: Must be registered on core resources via registerCustomRelations() in service provider's register() method
• Testing: Use php artisan migrate:fresh --seed to reset and test migrations
• Permissions: Register in service provider's register(), not boot()
